How the settings look untilnow.

This is not a bug, but an enhancement request.

In the mouse settings we have two possibilities to control the behaviour of the mouse:

1. Acceleration
2. Sensitivity

(There is a picture of this attached.)

But there is no setting for "mouse pointer speed".


What do I mean with "mouse pointer speed"?
--------------------------------------------------------
I mean this:
In a terminal we can change the mouse speed with this command: 
$ xinput set-prop 10 272 1

"1" is the default. We can set it to "0.6", then the mouse speed is faster:
$ xinput set-prop 10 272 0.6




How can we find out which numbers we have to type in for "10" and "272"?
--------------------------------------------------------------------------------------------
$ xinput list|grep -i mouse
⎜ ↳ Logitech USB-PS/2 Optical Mouse id=10	[slave pointer (2)]

(shows id of the mouse device)


$ xinput list-props 10|grep -i "Constant Deceleration"
Device Accel Constant Deceleration (272): 1.000000

(shows id of the device configurable option responsible for the speed)


$ xinput set-prop 10 272 0.6

(sets new value (0.6) for the device id and config. option i found)


Result: mouse speed increased. (decreasing value from 1.0 to 0.6 increased speed)

Note: When we boot the computer new, the setting for the gui
$ xinput set-prop 10 272 0.6 
will be resetted to the default "1".

To prevent this, it needs an entry in "Session and start behaviour" of XFce.


So my suggestion is:
--------------------------
Add two more sliders to mouse settings, both for "mouse pointer speed".

I have made a raw example for the first slider as a picture in the attachment. the first picture shows the slider for the roughly speed. 
"1" on the scale means, this is the default of "1". "2x" means, the speed is twice as high as the default. "3x" means, the speed is three times faster as the default.
"/2" means the speed is half as high as in the default. "/3" means, the speed is only a third of the default.

When we for example have chosen "2x", then the second slider (see picture 2 in the attachment), changes it's scale, so that it looks like in the attached picture 2. We have now the possibility to fine tune the speed of the mouse pointer between "1" and "3x".
